After acquiring the skill from the Fishing Guild Member, it automatically appears on the screen, even when the character is far from the water. The skill remains persistently available, even after the character restarts.
In official Lineage II Classic, the fishing mechanic has been automated: upon entering a valid fishing area, the "Start Fishing" icon automatically appears in the interface. Important: this icon appears even without a fishing rod and bait equipped. However, clicking it only initiates fishing if the character has the rod and bait equipped. Upon leaving the fishing area, this contextual button should not remain visible.
So, regarding the question:
“Should it appear only when approaching the water and using the rod?”
Almost. The retail Classic behavior is:
The character arrives at a valid fishing area.
The fishing button/icon appears automatically.
The rod does not need to be equipped for the button to appear.
To actually start fishing, the character must have a fishing rod and bait equipped.
Outside of a valid fishing area, the contextual button should not remain permanently on the screen.
